limiting straps

[centralchevyman]

I was wondering if anyone that has used limiting straps on the rear air bag setup had any pictures i could see the best way to mount them. Or do i even need them. Im just afraid of the bags overextending if i was to go over a bump fast. Any help would be great. thank you.

While it's not a good idea to use the shocks as a limiter either (for the same reasons it's bad for bags), most people let the shock to do the work of limiting. If it's going to be in the air for more than a few minutes of driveway floorjack action, I toss a tiedown around the frame and trailing arm and cinch it up. so neither the bag, nor the shock becomes the limiter.

If you are hitting bumps fast or hard enough that the suspension goes full travel then you got problems bigger than limit straps.

So other words this isnt something i need to worry about? i didnt know if it would be a problem cause ive never done air bags before and im trying to do it all myself and thats why im asking. thank you for the help

It's not a common concern. As mentioned your shocks will do the job under "normal" circumstances. Undue stress on your bags or shocks is not a good thing, but you shouldn't see that situation too often.

My shocks will go out farther than my bags will thats why im concered.

You need shorter travel shocks.

You can also check with your local 4 wd store, or online, and see what's available in limit straps. There are plenty of large suppliers out there who will carry products like you're looking for. There are even some that will build a strap to a custom length that you need.

If you do decide to go with a limit strap than I would measure to see where the bag is maxed out and get the strap slightluy shorter to prevent damaging the bag if the strap "grows" slightly under a heavy load.
I have a set of straps installed on my Excursion that is bagged so that I don't over extended the bag, or max the shocok out and possibly damage them as well. Granted my ride if lifted, but still I don't want to be going over a raise or dig while off road and over extend my suspension and damage something. Shown below is my ride that clears a 40 no problem and when the suspension articulates over it could easily damage an airbag.

I like to use limiting straps for several reasons. Mostly for the ease of loading a truck on a lift or putting it on jacks. It's nice to be able to drop the vehicle off at a shop and not have to tell them to do anything crazy with your truck. I use them on most vehicles. I often install bags so that they use about 3/4 of their total travel, because they seem to get much more stiff past that point. I use limit straps a bit past that point. I also like to build crossmembers that feature a full driveline loop, much like a race car would have, so sometimes limiting up travel is necessary to keep the driveline from coming in contact with the hoop. (Note: I do not do this with one piece driveline vehicles, unless IRS, because the driveline moves too far to get a decent amount of travel with a full hoop behind the cab). Most double wrap straps stretch about 1/2" under load, so keep that in mind. Quad wrap is probably less, but I have not used them much.

I never drive my vehicles high enough to use limit straps during suspension rebound, so I really don't use them for that. My average ride height is around 3 inches. I don't think they are necessary, but I do insist on using them on my own projects. I am often using shocks that vary between $100-300 each, and I am not keen on hanging a bunch of weight off of them.
